Find the slope from the coordinate points: (10, 25) and (55, 40)

The slope is 9/5

Step-by-step explanation:

To find the slope, we use the following slope;

m = (y2-y1)/(x2-x1)

Thus, we have

m = (55-10)/(50-25)P

m = 45/25 = 9/5

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
